These starching gives a very rigid support forthe lower extractor roll 22. The lever arm 29 is disposed in the space between the sides Ina. and lb. .The shaft 29' upon which it pivots is likewise supported at either end in the two sides. The head 29a of lever 29 is elongated so that the bearings for shaft 25 may be spaced at least as far apart as the bearings for shaft. This construction provides sufficie'nt rigidity to maintain the extracting rolls 2| and 22 parallel throughout the range of pres- I sures desired, while supporting the roll-s from only one side.

'To further facilitate positive and automatic delivery of articles from the starching rolls |4, l5 to the extracting rolls 2|,- 22 and awayirom the latter, there are provided a plurality of endless tapes 31, 38, 40 which are cooperatively associated with these rolls..' The tape 31 passes between the starching rolls I4, l5, between the extracting rolls 2|, 22, around a guide roll 4| and up over a tension roll 42, the guide 'roll beinglcarried by an adjustable arm 44, suitably connected, as by pivot means notshown, to the frame structure |0, and the tension roll 42 being mounted on the end of an; eccentric shaft 45 supported for rotative adjustment in'lugs 46 on the. top of the carrier l6 so 'asito enable the tape to be loosened or tightened as required. Thetapes 38, 40 pass around the lower extracting roll 22 and around a guiding and tensionadjusting-roll 41 carried by the adjustable arm 44. As articles-pass from between the extracting rolls 2|, 22, their positive and automatic delivery from the machine is effected. by reason of the fact that they are engaged by the lower reach of the upper tape 31 and the upper reaches of the lower tapes 38, 40.

As shown in Fig. 4, on the rear end of the extracting roll shafts 25 and 26 are intermeshing gears 35 and 36, so that such rolls, like the starching rolls l4 and I5, may be positively rotated in opposite directions, by means of any suitable mechanism such as an electric motor 48 driving suitable power transmission means such as the chains 49, 50 for driving the endless conveyors l2, the starching rolls l4, l5, and the extracting rolls 2|, 22 in a synchronized or properly timed relation. l p

While the foregoing description of an embodiment of the invention has been given in considerable detail to enable one to practice the invention, it is not intended to limit the invention to such details inasmuch as many modifications maybe made therein within the purview of the invention as defined in the appended claim.

What is claimed is:

In a starching machine including a pair of extracting rolls wherein after starch has been applied to part of a. garment in excess of the amount required that excess is removed by passing the starched part of the garment between the extracting rolls which have'their bearings only at one side, means for supporting and adjusting the pressure between said rolls for regulating the amount of starch removed without afiecting the alignment of the rolls comprising a rigid frame having spaced sides, a fixed mounting for one of said rolls including a first shaft rotatably mounted wholly atone side of the roll in bearings supported by said spaced sides, a lever disposed between said sides and pivotally mounted therein between its ends, a second shaft rotatably mounted wholly in one end of said lever parallel to said first shaft and supporting the other extracting roll from only one side, resilient means rigidly supported by said, frame, and a manually adjustable connection between said means and the other end of said lever operable to regulate the pressurebetween the extracting rolls.
